Given a positive integer n
, return the smallest positive integer that is a multiple of both 2
and n
.
Input: n = 5
Output: 10
Explanation: The smallest multiple of both 5 and 2 is 10.
Input: n = 6
Output: 6
Explanation: The smallest multiple of both 6 and 2 is 6. Note that a number is a multiple of itself.
1 <= n <= 150
class Solution:
def smallestEvenMultiple(self, n: int) -> int:
if n % 2 == 0:
return n
else:
return n * 2
